javascript停止工作$ .mobile.changePage（） [英] javascript stops working after $.mobile.changePage()
问题描述
我有两个页面：index.html和main.html
I have two pages: index.html and main.html
当我将main.html页面设置为我的应用程序的默认页面时，工作，但是当我将index.html设置为主要的时候，在重定向之后，main.html上的javascript只是停止工作。
When i set the main.html page to be the default page of my app, the java script works, but when I set the index.html to be the main one, after the redirect, the javascript on the main.html just stops working.
这里是HTML的两页：
here is the HTML of the two pages:

推荐答案
jQuery Mobile通过AJAX提取远程页面。当它这样做，它只拉在它找到的第一个 data-role =page元素。这意味着 data-role =page元素之外的任何内容都将被丢弃。
jQuery Mobile pulls in remote pages via AJAX. When it does this, it only pulls in the first data-role="page" element it finds. This means that anything outside the data-role="page" element is discarded.
是将您的所有应用程序的JS放入一个 custom.js 文件，并将其包含在每个页面的头部，这样，所有的代码为您的网站始终可用
The best work-around is to put all of your app's JS into a custom.js file and include it in the head of every page, this way all the code for your site is always available (to do this you will need to use event delegation).
您还可以将每个页面的JS放在 data-role =page 元素，因此它由jQuery Mobile抓取，而不仅仅是丢弃：
You can also put the JS for each page inside the data-role="page" element so it is grabbed by jQuery Mobile and not just discarded:
<div data-role="page" id="page1">
<script>
alert('hello');
</script>
<div data-theme="a" data-role="header">
<h3>
Header
</h3>
</div>
<div data-role="content" id="main">
</div>
</div>
